HEEIrATTACI-IING MACHINE.

maagea in- Heel-Attaching Machines, of which thev following description, in connection with the accompanying drawings, is a speciiicaf U tlon, like reference characters on the drawi' l'ffings indicating like parts in the several iigures.

rllhis invention relates to heel nailing'mag chines. The machine shown includes mechanism for 'subjecting a heel and shoe to presg-,sure 'and means for driving nails through the parts so held under pressure. It will be apparent that as far as the mechanism for applying pressure to the shoe'and heel is concerned it could be employed advanta- -gq ,geoously in machines not equipped with nail' driving means, for example 1n sole laying machines or sole leveling machines. Itwill be'understood therefore that features of the invention may be embodied i-n machines for zur other purposes than attaching heels to-shoes. Heel attaching machines are in common use lwhich include a stationary nail block and a jack which is movable toward and from the nail block, the attaching pressure being 9,914 applied to the shoe and heel by movement of the jack. Other heel attaching machines are incommon use in which the nail block is movable and applies pressure to the shoe and' heel by its movement toward the'jack. While many features of the present invention may be employed' in machines of either of these two types. the. machine hereinl shown is `provided with amovable nail block for the purpose of applying attaching pressure a@ tothe shoe heel.

In the machine herein illustrated a jack is arranged `lor movement toward the nail `block to bring a shoe .and heelinto preliminary engagement or to measure the work, as it issometimes termed. After the shoe and heel have been brought into engagement the nail block is automatically moved toward the jack a predetermined distance to sub-` ject the shoe and heel to attaching pressure. After the attaching pressure has been applied the nail drivers areuautomatically actuated to drive. the attaching nails. In.

bringingthe sho'e and heel into preliminary engagement it is ldesirable that the prelimij 5s; nary or measuring pressure beof a proper Specification of Letters Patent.

movement of' the -nail block may not' bring v lthe shoe and heel intosuficiently firm engagement, and if it is 4excessive it will be obvious that the attaching pressure may becomeI so great. as tocause liability of breaking. thelast 1n case the rshoe is heeled upon the sists in means for limiting the preliminary pressure applied tothe shoe and heel. 1n the particular embodiment of the invention shown, the jack -is moved?` manually ntoward the nail block and the mechanism for imparting movement` to the jack is so con.-

.structed that the pressure appliedv to the shoe and heel through the jack can never rise above a certain maximum measured by the' tension of a spring-"included in said mechanism.

A further feature of the invention con-- aus,t

sists in the provision of a single lever to be ment of the nail block and the nail drivers"A working therein.l According tothearra-ng'ement shown,-by an initial movement of this' member the jack is moved toward the nailblock to subject the shoe and heel to a preliminary pressure and by further movement of said member the machine is started to effect the automatic movement of the nail block, for subjecting the shoe and heel to attaching pressure, and the subsequent movement of the nail drivers to drive the attaching nails.

'Tovprevent yielding movement of the ack away from the nail block during the application of the nal or attaching pressure to the heel there'is providedv a device for l'ock'- ing the jack in clamping position which is constructed to be rendered effective when the shoe and heel are brought into engagement in the preliminary pressure applying movement.

In the preferred embodiment of the invention there is provided a fluid pressure mechanism for locking the jack frommovement away from the nail block which is arranged to`be rendered effective upon the clamping free of the work. In accordance with a convenis controlled is arranged to control -the fluid ient construction the lever by which the j ack' l A 25 determined distance to apply the final or mechanism for preventing separating move- ,ment of the clamping members comprises a pressure chamber `having" aV part yarranged Yforrr'iovement to varyy the size of the chamber which 4is" associated with the jack and arranged to control its position, a passage way leadinggfrom the pressure chamber, a -`,valveA for openingand closing the passageway andmeans lfor actuating the valve to close Vthe passageway arranged to be thrown into Ioperation by the clamping of ther work.

Y'Upon the closing' of the valve in the pas# sageway the part that is arranged for movement to vary the size of the pressure chamber Vj is locked ,from 'movement and the ja'ckbeing associated with Vsaid part isl locked from movement away from the nail block so that .thework may be compressed or nails driven so: Y Y

.The present embodiment ofthe invention vis herein shown applied to a heel attaching machine of the type in which theshoe and `heelare sustained in proper. relative positionpabove a nail blockzprovidedl with the usual nail conduits and drivers for the purposeof driving *attaching nails into the heel andtshoe. The nail block is arranged to be Y moved unwardto force the heel in engage;

` In the drawings, 2 designates a head in which is located` the nail block which may be provided with the usual nail conduits and Vdrivers l3 and with any suitable means for actuating the nail drivers. Ashoe sup'- port' is arranged above the nailv block and block.` Suitable automatic means is Valso provided for raising the nail block a preto close the lower end of said sleeve.

attaching pressure to the work and to hold the work under such pressure while the attaching nails are driven into the work. This means for elevating the nail block may be similar to the mechanism employed in the machine shown .in United States Letters Patent to Pope 446,885, for raising the `jack to apply the final or attaching pressure to the work and, as shown in Fig. 4, comprises a pair of eccentric cams 5 which are oscillated by connections with side rods 11 extending upwardly from the cross-head `13.7and sliding at their upper ends in sockets in the frame 10.` The upper of the cams 5 is journaled in a vertically movable carriage upon which the head 2 with the nail block is mounted.V The cross-head 13`is reciprocated vertically by an eccentric on the forward end of themain shaft and when its upward movement takes place the carriage 15 and the nail block are lifted bodily t0- ward the shoe support. The nailing mechanism comprises the drivers 3 carried by the driver block 7, the plunger 17, and the actuating rod 9 connected at its lower end to the cross-head 13. In the present construction the shoe support comprises a jack post 4 which is provided with an upwardly extending sleeve 6 fitted to slide vertically in Y a cylinder 8 which constitutes part of the frame 10 of the machine. The sleeve 6 and jack post 4 are maintained normally at their upward limit of movement by a spring 9 that is attached at its ends to studs 12 and 14, projecting respectively from the jack post 4 and cylinder 8.

Within the sleeve 6 is arranged another sleeve 16 restrained from vertical movement by a flange 18 which projects trans vversely from the upper end of said sleeve and is received between a cap piece 20 and the upper surface of the cylinder 8. The cap piece 20 is recessed to receive the flange 18 and may be secured to the end of the cylinder by screws or by other means. The recess in the cap piece 20 is preferably of such size as will enable the sleeve 16 to move laterally so as to permit it to adjust itself into such relationship with the sleeve 6 that the' latter will be enabled to slide freely in a vertical direction. The sleeve 6 is` adapted to contain a Huid such as oil and 'is provided with a valve seat 22 'at its lower' end into which a mushroom valve 24 is formed to-fti so t wi be observed in the construction described that the lower portion of the'sleeve 6 constitutes a Huid ,pressure chamber and that the lower end of the sleeve `16 forms a passageway leading from the chamber, which passageway is .controlled by"\the v alve .24. for movement toward and from the nail i The valve 24 is secured to thelower end of:

a valve rod 26 which extends"upwardbr within the sleeve 16 and through an opening formed in the top of the cap Vpiece 20.

ineen@ Fig. 3, by means of which anda link 38 the rear'end of the lever 34 is connected with thel rearl end of the lever 30. i The upper lend of a rod'40 isY also connected to lthe rear end of the lever 34 by means of the connection 36.

The connection 36 is constructed to providev for the angular movements of the link 38 and the rod 40 and to this end said connection comprises a cylindrical plug 42, mounted in a bearing in the end of the lever 34,

into which the upper end of the rod 40 isv securedV by threaded engagement. ,The lower end of the link 38 is secured by threaded engagement in a pin 44 that is mounted to turn in'a bearing formed in the plug 42. ySuli cient .space is left in the socket around the link and rod to4 permit of vtheir angular movement when the lever 34 is actuated.

The link 38 is pivotally connected to the rear end of the lever 30 by a connection which -permits the link to yield upwardly independently of said lever. In the construction shown, the link 38 passes through a boss 48 pivotally mounted on the end of the lever 30, Vand a coil spring 50 arranged about the link with its lower end in engagement with a collar 52 has its upper end in engagement with said boss. The rod 40 carries a. catch 54 which is" adapted to engage the end o f one arm 56 of a bell-crankV lever pivoted upon the frame of the machine, the other arm 58l of which is connected by a link 60 with one end of a lever 62 which may control the starting clutchin the manner described in United States Letters Patent toPope, 446,885, the arrangement being such that when the lever 456 is raisedthe lever 62 will be moved forwardly out of engagement with the clutch dog so that the machine will be started to render the'nail drivingr mechanism operative. The catch 54 is provided with a spring 64 which tends to hold it in contact with the end of the lever 56. A radius arm 66 pivotally mounted upon the frameof the machine and having its rear endpivotally connected to thev lever .40'is'adapted to move thecatch piece rearwardly in opposition to the spring 64 when the lever'56 is raised to start the machine. After the lmachine has been started and the catch piece has been movedrearwardly a sutlicient extent' to free' it from engageme t with the endfo the' lever 56 the latter 1s moved downwardly by a spring 68 so that. through the mediuxnof the link 60, the lever 62 will be` moved rearwardly to aposition in stop the machine at .the completion .of one revolution of the drivi shaft. connection .between the lever l 56 andthe rod 40 is restablished when the hand lever ,34 is returned to its initial position. A `lioat 70 arranged within the sleeve 16 and constructed to surround the valve .spindle '26. lis adapted .to .serve as afspla'sh-preventing device and to prevent the ejection .of the liquid from the .sleeve during the rapid manipulation of the jack post.

In the operation of the machine vshown the shoe to be heeled is placed upon .the jack 4 andthe heel is placed in proper position upon the nail block beneath the jack. The

operator thenvgrasps the handle of the leveil 34 and turns the lever upon its pivot 36 so .as to bring the shoe 'down upon the heel' and place the latter under a certain amount of manual compression. During this movement it will be observed that the jack .4 is lowered 'in opposition to the spring 9. Owing to the resistance offered b y the spring 6 8 during the" downward movement of the jack the connection. 36 is vrestrained nom rising and in consequence the' lever 30 "will remain unoperated and `the valve ,24 will be kept away from its seat solas to permit .free interchange. of fluid between the interior of the sleeve 16 and the fluid-pressure chamber below -the valve. movement Yof the .jack 4 is retarded by .the engagement of the shoe with the heel, the

rear end of the lever 34 will be lifted in they further actuation of said lever to effect through the link 38 `the actuation pf the 1ever'30 to lclose the valve 24. Upon the closing of .the valve 24 the passageway leading from lthe fluid .pressure chamber is lclosed so that the jack 4 is locked from up- In the further actuation ward movement. of the'lever 34 the rear end of said lever as it' moves upward will, through the agency of the connecting mechanism previously described, cause th lever 62 to'move outA of the path of the clutch dog so that the machine will be' started'. Upon thestarting Iof the machine, the nailv block is'clevated to apply the iinalpressure to the heel and the attaching nails are driven into the heel by the nail driving mechanism. When the nailing operation has been completed the lever`34 is swungupwardlyby the operator and moves first about its fulcrum 35, which is held stationary until the valve 24 has been opened.

AfterV the valve has been opened, further" movement of the lever takes place about the fulcrum 36, the jack 4 being thereby elevated to its initial position..

The amount of" liquid imprisoned in the Effective path ,ofthe .clutch dog and .enable ,to

ljVhen the downward' roo fluid pressure chamber beneath the -valve l24 lwill vary according to the'extent the jack has `been lowered, which will depend upon the thickness of the heel operated upon, but

whatever may be'the amount of liquid be-k lowthe valve it will afford a firm abutment for the heelduring the application `of the heavy'final pressure exerted by the machine and the subsequent driving ofzthepnails. The provision of the spring in the-connection of the link 38 with the lever -30 perv mits the necessary lost motion of the link 38 after the valve 24 has been closed and while the starting device is being actuated.

It will be seen in the construction .shown that the amount of preliminary pressure which `may be applied to the heel andshoe bythe actuation of the'lever 34" is limited by the tension of the spring 68, so that the application of an excessive preliminary pressure to the work is prevented.
